Mr Dobbin, one of 30 MPs wanting more detailed information from the Department of Health, went on: "Teenage pregnancy is rising and this is leading to a rise in sexually-transmitted diseases. We are seeking the statistics about underage pregnancy in Rochdale.

"Statistics are normally collated regionally, but this means that locally people don't know the results. We have written to Rochdale Council asking that information is made available to schools and clinics. Some of the statistics are available in Rochdale at the moment, but we want to look at the trends to see if government investment is working."

Mr Dobbin's comments came following a report by the director of the department of economics at Nottingham University, Dr David Paton. It found that provision of family planning facilities to young people increased, rather than decreased, sexual activity among girls below the legal age of consent.

The Department of Health has pressured for contraceptive and abortion facilities for the young. The policies adopted by the DoH include giving girls as young as 11 access to abortions and the morning-after pill without parental consent. It claimed these policies would lower teenage conception rates.

A suggested motion put forward by the group of MPs requests that the DoH and Primary Care Trusts publish information about the rates of young people attending family planning clinics and receiving the morning-after pill. The motion asks that rates of teenage pregnancies, abortions and sexually transmitted infections are also revealed.

Britain now has the highest rate of teenage pregnancy in Europe and the second highest in the world.

Mr Dobbin added: "This is not about the morality of abortion or about the morality of distributing contraception to the very young. It is about the morality of adopting strategies when there is no clear indication as to their potential success and a considerable amount of evidence as to the damage they can do."
